Where to Sow
Early sowing can be made under glass in pots or seed trays, sow seed on the surface of seed sowing compost and lightly cover with a sprinkling or vermiculite or compost, and place at a temperature of 14C. Outdoor sowings can be made in April, sow seed thinly in shallow drills 1.5cm (1/2in) deep, with rows spaced 30cm (12in) apart.
What to do next
Greenhouse sown seedlings can be pricked out into individual pots or modular trays. Move plants to a cold frame in April to harden off before planting outside 15-20cm (6-8in) apart. Outdoor sowings can be thinned gradually until plants are 15-20cm (6-8in) apart, then leave to mature as smaller bulbs for storing.
Lift bulbs in autumn when mature and allow to dry before storing in a cool place for winter use.
